This was one subject that Ed Miliband has campaigned heavily on. So now that gas companies are listening, Ed can really push is message about pushing for gas companies to freeze their prices.
Ed did well again I don't think David Cameron had really prepared himself to answer questions on the energy.
David Cameron made little attempt to answer the questions put to him. He just really focused on personally attacking Ed Milliband and he will probably hope that this looks good to the wider audience.
Ed did well and hopefully he will carry it to the General Election and beyond.
